If you really wanted to update the camera application, I suspect there is a good chance you could just install the version from the Froyo build. You might have to fiddle around for awhile to get it to work. But here's the question: do you really want to waste all that time? The camera on this thing is pretty terrible. It would probably be useful for video chat, but I've had trouble getting Skype to work.

You can actually get most of the gapps to work. If you're interested in Gmail, Android Market, and so forth, you can find instructions on this thread:
